  render() {
    return (
      <CheckBoxComponent label="Default" />
    );
  }
}
import { CheckBoxComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';
import './App.css';
// Import the CheckBox.
// To render CheckBox.
export default class App extends React.Component {
    render() {
        return (<CheckBoxComponent label="Default"/>);
    }
